I was out with one of my final test drives, everything was good until I pulled up to my shop gate, shut the car off to open the gate and when I went to re-start, nothing happened.
I dragged the car back into the shop and checked the battery, the voltage was good and I had no trouble starting the car earlier that morning several times so I immediately blamed the Chinese 12 volt solenoid that has previously given me trouble. Went to NAPA and bought a Ford 12 volt solenoid, pulled the starter and modified the solenoid to fit. Bench-tested the starter and re-installed. Ouch! Still no start! All indications are now that there was a sudden failure of one or both of the 6 volt Optima batteries. I'm kicking myself for not having by jumper box charged before deciding to remove the starter! I had no way of load testing the batteries and they are a real chore to remove to be tested. So I grabbed a 20% off coupon and headed to Harbor Freight to buy a 100 amp battery load tester. Total cost, $16 plus tax. Tested the batteries in the car at 12V and sure enough there was a problem. Removed the batteries and tested each at 6V and one was totally dead and the other was marginal. One was bought in 2015 and the other in 2016. Ordered a new pair of 5 volt Optimas for $375 and waiting for them to be delivered. Lesson learned, don't jump to conclusions, check all options first and suspect the less obvious!
